1EmeraldEnhances Critical Damage against Vulnerable enemies.

Diablo 4 has seven Gem types, each with unique effects when applied to equipment. Gems work on Weapons, Armor, and Jewelry, with the Best Weapon Gem elevating your Build, regardless of class.

For Weapons, prioritize Damage Effects, as Gems can be game-changing or have minimal impact. Consider your weapon type and class when choosing Gems.

NOTE: It is crucial to understand that some weapons are locked for specific Diablo 4 classes. For example, the Rogue can only use bows, and Barbarians can use two-handed weapons.

1. Emerald

Weapon Effect 6% increase in Critical Strike Damage to Vulnerable Enemies. 7.5% increase in Critical Strike Damage to Vulnerable Enemies. 9% increase in Critical Strike Damage to Vulnerable Enemies. 10.5% increase in Critical Strike Damage to Vulnerable Enemies. 12% increase in Critical Strike Damage to Vulnerable Enemies.

  • 3 Chipped Emeralds
  • 12,500 Gold
  • 3 Emeralds
  • 18,000 Gold
  • 3 Flawless Emeralds
  • 50,000 Gold

The Emerald Gem enhances weapons, armor, and jewelry, providing a unique advantage: increased damage against Vulnerable enemies.

Vulnerability, a debuff applied by certain class skills like Enhanced Flay for Barbarians and Flickering Frost for Sorceresses, results in a 20% damage boost to affected enemies.

When your weapon consistently applies vulnerability, the Emerald Gem becomes a game-changer. It’s especially effective against Diablo 4 Bosses.

2. Diamond

Weapon Effect 4% increase in Ultimate Skill Damage. 5% increase in Ultimate Skill Damage. 6% increase in Ultimate Skill Damage. 7% increase in Ultimate Skill Damage. 8% increase in Ultimate Skill Damage.

  • 3 Chipped Diamonds
  • 12,500 Gold
  • 3 Diamonds
  • 18,000 Gold
  • 3 Flawless Diamonds
  • 50,000 Gold

To enhance your weapon’s performance, obtain a Diamond gem. While not ideal for early/mid-game, unlocking an Ultimate Skill from your Class’ skill tree becomes crucial in the endgame.

Ultimate Skills, located at the skill tree’s bottom, such as the Grizzly Rage for Druids, significantly boosts your damage when used, depending on the gem’s rarity, notably the Diamond Gem.

For those relying on Ultimate Skill Damage in Diablo 4, the Diamond Gem excels, making you unstoppable. It complements late-game Druid, Rogue, and Necromancer Weapons.

3. Amethyst

Weapon Effect 4% increase in Damage Over Time. 5% increase in Damage Over Time.  6% increase in Damage Over Time.  7% increase in Damage Over Time.  8% increase in Damage Over Time. 
Level 15 20 40 50 60
Cost None
  • 3 Crude Amethyst
  • 4,500 Gold
  • 3 Chipped Amethyst
  • 12,500 Gold
  • 3 Amethyst
  • 18,000 Gold
  • 3 Flawless Amethyst
  • 50,000 Gold

The Amethyst Gem is the go-to choice for players relying on Damage Over Time (DoT) effects in Diablo 4. DoT effects like bleeding, burning, poison, or blight damage are familiar to experienced players.

DoT effects inflict lasting damage on enemies even without direct hits. Barbarians excel in Bleed builds, and if you use Hellhammer (Mace) or Fields of Crimson (Sword), Amethyst significantly enhances their effectiveness.

In summary, for Bleed or Poison builds on Necromancers, Sorcerers, or Rogue Weapons, prioritize the Royal Amethyst for an 8% boost to your DoT damage in Diablo 4.

4. Sapphire

Weapon Effect 6% increase in Critical Strike Damage to Crowd Controlled Enemies. 7.5% increase in Critical Strike Damage to Crowd Controlled Enemies. 9% increase in Critical Strike Damage to Crowd Controlled Enemies. 10.5% increase in Critical Strike Damage to Crowd Controlled Enemies. 12% increase in Critical Strike Damage to Crowd Controlled Enemies.
Level 15 20 40 50 60
Cost None
  • 3 Crude Sapphire
  • 4,500 Gold
  • 3 Chipped Sapphire
  • 12,500 Gold
  • 3 Sapphire
  • 18,000 Gold
  • 3 Flawless Sapphire
  • 50,000 Gold

The Sapphire Gem adds a low-key effect on your weapon. It may not help you take down the Diablo 4 Bosses, but it will surely help you deal with hordes of enemies. With the Sapphire Gem, you will be able to increase critical strike damage on crowd-controlled enemies.

Crowd Control effects usually slow down a bunch of enemies at once. Players can also inflict some crowd control effects, which decrease damage received. To be more precise, some of the Crowd Control Effects include:

  • Slow.
  • Immobilize.
  • Knockback.
  • Stun.
  • Freeze.

Crowd Controlling is usually associated with skills. Rogues can use some of their skills to Daze enemies. Whereas Barbarians can stun their foes. Regardless of your class, build, and weapon, the Sapphire Gem is worth considering if you’re relying on Crowd Controlling AoE attacks. In my opinion, Sapphire is a great Diablo 4 gem for Rogue Weapons.

5. Topaz

Weapon Effect 10% increase in Basic Skill Damage. 12.5% increase in Basic Skill Damage. 15% increase in Basic Skill Damage. 17.5% increase in Basic Skill Damage. 20% increase in Basic Skill Damage.
Level 15 20 40 50 60
Cost None
  • 3 Crude Topaz
  • 4,500 Gold
  • 3 Chipped Topaz
  • 12,500 Gold
  • 3 Topaz
  • 18,000 Gold
  • 3 Flawless Topaz
  • 50,000 Gold

The Topaz Gem significantly boosts Basic Skill Damage, making it a valuable choice in Diablo 4. It offers up to a 20% increase in Basic Skill Damage, benefiting all classes. Whether you play as a Necromancer, Rogue, or Sorcerer, this gem enhances your weapon’s performance on the battlefield.

For early-game Necromancer weapons, in particular, the Topaz Gem provides a much-needed power boost. Adding Topaz to your weapon slots can help you breeze through the initial stages of the game.

Additionally, consider the Ruby Gem, which adds extra Overpower damage to your weapons and is also a solid option.

How To Get Gems In Diablo 4?

There are several methods you can employ:

  1. Enemy Drops: Defeated enemies have a chance to drop Gems, with the rarity of the Gem typically corresponding to your character’s level. Crude Gems are commonly dropped at lower levels, while higher-level characters may find more valuable Gems.
  2. Chests: Explore the open world and open chests to potentially discover Gems. Chest rewards are randomized, but there’s a chance to obtain Gems from them. During events, the drop rate of Gems from chests may increase.
  3. Jeweler: Visit the Jeweler NPC to interact with Gems and Weapon Sockets. The Jeweler can add sockets to your equipment, upgrade Gems, and remove Gems from your gear. You can unlock the Jeweler and their initial quest, “Gem Crafting,” after reaching Level 20.

When it comes to upgrading Gems:

  1. Gem Rarity: Gems come in various rarities, from Crude to Royal, with five rarities in total. The higher the rarity, the more potent the effects of the Gem.
  2. Upgrading Process: To upgrade a Gem, you’ll need to provide the Jeweler with the prior rarity Gem and a certain amount of gold. Upgrading Gems enhances their buffs, making them more effective for your character’s progression.
